vroron n. fiARBERT, or srainermrn, rumors -nnrarivrne-vanvn Heada- Applicat io n filed September Retaining valves are applied to cars to 1 make movement of train safe, and to consorvethe supply of air, and this valve, when set and in good working order, does not al: low all of the air to escape from the brake cylinders, but retains a certain amount of pressure therein sufficient to hold the brakes in a set position, while the air is being replenished in the train line. When the a1r pressure in the line'is increased or replenished, if the retaining valve is in an lnoperative condition, the triple ,valve will automatically assume a released positionallowingall of the air to escape from the brake 1 cylinder, releasing the brakes, and allowing the train to gain momentum, and run out of control. It is, therefore, of the utmost im-' portancethat the retaining valve be in good a working order at all times. I

Retaining valves have in the past been secured to cars by lag screws andby bolts, the retaining valve being located on the out- .side at the end of the car and near the top of the car. When bolts are used, andthis has been the most universal way of securing valves to the car, the bolts extend from the inside. of the car, the nuts on the. end of the bolt being on the outside of the car. This type of fastening has been found objectionable from many standpoints, in that thelag screws and bolts work loose to such an extent that the service movements 'of a car tend to give a sidewis e movement to the retaining valve, which, with the pipe leadmg from the air brake system of the car, moves somewhat after the fashion of a pendulum. Such condition is prohibited bythe United States safety appliance laws, inasmuch as it reduces the efficiency of the brake system, besides endangering the lives oftrainmen.- Another objection is that in case of bolts,- the heads of which are on the inside of the 7 car; if these bolts become loose during transit, the only way to get at the bolt is to unload the car, which can only be done at great expense, and sacrifices the safety of; the goods removed from the car, and inwardly creases the liability of the railroad for damage and stolen goods.

The object of my present invention is to provide an anchor for a retaining valve, especially adapted for attachment to the corrugated steel ends nowso generally-used on freight cars, the anchor being so designed for snug application to one of the corrugations of the steel end of a car so that the 16, 1925.

Figure l is a top plan view of FigureQQ, I

The reference numeral (1) designatesa fragmentary portion of a. corrugatedsteel end of a car, the retaining valve being designated by the reference numeral (2) to which the air pipe (3) is connceted, said air pipe being connected up with the air brake system of the car.

, My improved retaining valve bracket comprises a base (4) having suitable bolt or rivet openings (5) at the upper corners through which the rivets (6 are adapted to pass whereby the. anchor is rm'ly and rigid ly secured to the end of the car. This base a retaining Figure 3 is an end elevation of Figure l) is also provided with slots (5) in its side I edges, connected with elongated slots (6) vertically disposed whereby the bolts (7) may be passed through the slots (6), to se'-- cure the retaining valve (2) to the anchor.

In the first application of the valve to the anchor, the bolts 7 will be placed at the upper ends of the elongated slots (6), so that in the event of the shortening of the air pipe (3), for any reason, such for in stance asrethreading the upper end of; the

tion with the retaining valve, the bolts may be adjusted to lowered positions in the pipe in case ofbreakage-at the connec-' slots ('6) as will be readily understood by those skilled in the art. 5

I provide thebase plate extending strengtheningv rib or flange (8). There may be as'm any of these (4) with a reari flanges as may be desired orrequired bythe railroads, and theseflanges terminate at their upper ends in concave seat (9) adapted to Y receive the upper portion of one of the cor-v rugations of the steel end (1'). It will '-be' noted inFigure 1 that the upper'end of the [concave seat extends inwardly as at on the corrugation to which it is secured'so that the concaved seat (9) substantially hugs the apex portion of the corru-v gation to which the anchor is secured, there by assisting very materially in intimately connecting the anchor with the corrugation with a maximum of bearing contact or sur face between the corrugationand thean ohor. This extended seat contact and overlapping of thecorru'gation by the anchor also reduces 'to'a minimum the liability of 'thelrix ets (6) being shealte'd.
